Hiked up to a rural lake last week in Yellowstone in an attempt to get some otter pics, something that has eluded me during 8 previous trips. Had no idea I would be walking into this scene. Upon getting there two hikers informed me that there were two courting grizzly bears at the opposite end of the lake. I got there just in time to see the one bear leave up over the hill. The second griz remained, coming down to the edge of the lake, staring down an otter as the otter curiously & cautiously checked the bear out, went for a swim with the otter, chased after some waterfowl then made its' way over to a boulder for a good ole bath and back scratch. Pics of the show. Video link at very end Griz was 270 yards across the lake from me.
